- CLAMP,

7 Application filed December 16, 1907. Serial N 0. 406,661.

To all whom it concern:

Be it lmownthat I, Bnnr A'. PETERSON, a

citizen 'oflthe United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Clamps, of

which the following is a specification.

One of the objects of this invention is to provide a clamp which shall be stronger, less i Another. object of the invention is the provision, in a clamp having a member provided with a friction surface, of means for removably securing-the friction surface to'said vmember.

A further object is to obtain a spring clamping action in a clamp of the tongue and groove type.

The invention also relates to the otherim' provements in clamps hereinafter set forth. v

In the accompanying drawings, Figure 1 is a fragmental side elevation of a clamp embodying the features of my invention. Fig.

, 2 is anend elevation of said clamp. Figs.

preferably formed of metal. The'section 1" is made from an integral'strip of sheet metal bent to provide two arms 3, the edges of said strip being brought together at what may be termed the under side of the clamp,

and there connected together in any suitable way, as, for example, bybending one edge portion to form a groove 4 in which theother edge 5 of said strip is adapted to lie.

The arms 3 form between them a groove 6 extending throughout the "length of the clamp section 1 In order to obtaina spring clamping action when the tongue sectlon 2 is pressed into the groove 6, said groove is preferably made-somewhat narrower at its.

upper open end than in its lower portion.

The tongue section2 may be made ofan integral strip' of sheet metal folded to form two sides 7 and a groove 8 in the upper portion of the tongue section. The upper end Specification of Letters Patent.

of the groove 8 is preferably somewhat narrower than the lower portion thereof. The edges of the strip from which the tongue' section 2 is formed meet at the lower edge ofthe section, and may or may not be rigidly connected together. shown? as'merely bent inward and held in Said edges are herein contact with each other by the resiliency of the material of which the section is formed.

When the clampis to be used for holding such articles as warp threads, for example, it is desirable to provide a friction surface upon one of the two sections of the clamp. I

have herein represented such a surface as applied to the tongue section. With a View to convenience in applying and removing said friction surface, I may give the material which affords said surface the form of 'a tube 9, said tube being adapted to receive within it the tongue sect-ion 2. The tube 9. may be formed of a strip of felt or other suitablematerial, the longitudinal edges of which are united by stitches 10 or in any other desired way. Preferably the tongue section 2 is inserted into the tube 9 so that the seam in the tube lies above the groove 8 in said tongue. r

The friction material is' removably secured to the tongue section 2, in this instance, by means of a member 11 which may be of'the samelength as the'tube 9 and the i friction material'to the tongue section and stretch said material over the outer sides of said section. The member 11 preferably comprises two curved portions 13 adapted to fit over the upper part of the tongue section 2. v

In use, the article to be secured in the clamps, as, for example, a sheet of warp threads, is laid across the groove 6- in the section 1 of the clamp. The tongue-section 2 is then placed over the article and pressed into the groove 6, carrying before it into said groove a portion of the article to be clamped. The arms 3 of the clamp-section l'yield outward slightly when the tonguesection 2 and the article being clamped are placed in the groove 6, the resiliency of said arms causing the article to be held securely Corrections in Letters Patent llet .1991 ,640. 4

in the clamp. When the article is to be released from the clamp, the tongue section 2 is withdrawn from the groove 6. When the friction material covering the tongue section '2 becomes Worn it may be removed by withdrawing the member 11 from engagement with the tongue section 2. Said tongue section may .then be drawn out of the tube-9, inserted into a new tube, and said new tube secured to the tongue section by means of the member 11.

It is obvious that many changes may be made in the embodiment herein illustrated of m invention. I, therefore, do not limit inyse f to the precise details above set forth.

I claim as my invention:

1. A clamp comprising a grooved member formed from a strip of sheet metal bent to rovide tworesilient arms form'in a groove between them, the edge portions 0 said strip being brought together at the under side of the clam section; and a tongue section.

2. A 0 amp comprising a member having agroove therein, said groove being some- ,in its lower portion, the arms formed by section adapted to enter said groove and be held therein by, the Spring clamping action of said arms. i

3. A clamp comprising a section provided with a friction surface, said surface beingaflorded by a tube adapted to receive said case the Patent Oflice.

4. A clamp comprising a section provided with a friction surface, said surface being afiordedfbv a tube adapted to receive said section, said section having a groove therein,

and a member adapted to lie in said groove for securing said tube to said section.

grooved member formedfrom a strip of sheet metal bent to provide a groove in said member; friction material; and a member said material to said member.

a curved portion at eachside of said tongue adapted to overlie a portion of said tongue section.
